Relationships Γ— Movement & Health

Frequently Asked Questions

Everything you need to know about privacy, billing, and how Cairn Harmony works.

Is my personal data ever uploaded to external servers?
Never. Cairn Harmony is built on an uncompromising offline-first philosophy. Your entire database lives inside your iPhone's protected memory, encrypted with AES-256 (SQLCipher). We operate no user analytics servers, require no account registrations, and never sell data.
What happens if I change or lose my iPhone?
Your records sync smoothly through your own personal iCloud Private Database with End-to-End Encryption (E2EE). When signing in with your Apple ID on a new device, your data restores automatically. Nobodyβ€”not even Apple or the Cairn teamβ€”can decrypt your files.
Why is the Camera OCR receipt scanner completely free?
We harness the Apple Neural Engine directly on your iPhone using the native Apple Vision framework. Because scanning runs locally on your chip without incurring expensive third-party cloud API costs, we can offer unlimited instant receipt scanning completely free of charge.
Is the Lifetime Pass truly a one-time purchase?
Yes. With a single $119.99 payment, your Apple ID permanently unlocks all Plus features without any recurring fees or renewal charges, plus future access to the upcoming Cairn Together shared couple/family space.
Does Cairn Harmony use cloud generative AI (like ChatGPT)?
No. Cairn Harmony is powered exclusively by deterministic mathematics and validated behavioral science frameworks (RULER, Dunbar, CBT-I, SDT). All scores, balances, and reflections stem from transparent formulas, completely free from generative hallucinations.
